IMPROVEMENT IN CULTIVATORS.

Specifica-tion forming part of Lettersv Patent No. 30,709, dated November 27,1860.

To all 'whom 'it may concern.'

Be it known that we, JAMES H. ANDERSON and EDWARD H. ANDERSON, both of Easton, in the county ot Talbot and State of Maryland, have invented a new and Improved Cultivator; and we do hereby declare that the following is a. full, clear, and exact description ofthe same,reference bein g had to the annexed drawings, making a part of this specification, in Which- Figure l is a side sectional view of our invention Fig. 2, a plan or top view of the same.

Similar letters of reference vindicatecorrespending parts in the two figures. f

lIt is weil known to agricultnrists that the ordinary cultivators ywhich are employed for pulverizing the soilnderadicatingu-.eeds from growing plants in hills and drills injure the young and .tender roots which are nearI thc surface of the ground and v which serve as the main feeders for the plants.

The object of this invention is to obviate this difficulty and at the same time cause the earth to be thoroughly pulverized and loosened. To this end we employ a cast-metal or a wooden shoe shod with metal, provided' with suitable handles, and having a toothed cylinder behind it, all constructed and arranged to operate, as hereinafter described, to eii'ect the desired end.

To enablevthose skilled in the art to flly` understand and construct my invention, I will proceed to describe it.

A represents a shoe. which is somewhat in the shape of a boat, Ine front. being of curved form and meeting in a point, the bottom tlat, and the back at light angles with the-back parts of the sides ot' the shoe. This shoe may be of cast'iron, in one piece, or it may be of'.

wood shod with metal at its bottom.

To each side ofthe shoe A there is attached a handleLB. These handles are inclined'to an angle about equal to that ot ordinary plow or cultivator handles. (See Fig. 1.)

To the back part of the shoe A, at each side, there is attached an arm, C. These arms are each attached to the shoe by a. single bolt or pivot, a, and the outer ends of the arms C are connected each by a rod, b. The arms C arc connected each by aber, D, witlrthc handles B B, the bars I) beingpert'orated with a series of holes, through either ot' which pins c pass into the arms C.

Between thel two arms C (l a cylinder, E, `is placed and allowed to rotate freely, thc shaft dot" the cylinder having its bearings in the arms C O. The cylinder E has its periphery provided with radial spikes or teeth c.

The operation is as follows: The draft-animal is attached to the front end of the shocA. The shoe, as the implement lis drawn along, crushes ail clods and completely pulverizvs the earth, while the toothed cylinder E loos-' ens up the soil, rendering it permeable to vair and moisture without at all injuring the roots of the plants.

The teeth c may be made to penetrate thc earth at a greater or less depth by adjusting thecylinder E higher or lower, which is done by placing` the pins c in different holes in theV bars D D.

The draft of thisimplement will be lighter l than those constructed in the ordinary way. `I-t may be readily turned from `one row into another, can be used in the driest weatherthe more frequently the better-and the shoe A may be supplied with stones to regulate the weight of the implement accordingto the work to be performed; v

Any proper-shaped teeth may be used on the cylinder E; but those of ordinary straight form will probably answer as good a purpose as any. .I

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is

v The combination ot the shoe A and toothed cylinder\Econstructed and arranged to operate substantially as and for the purpose set forth.
